使用Python批量将.ncm格式的音频文件转换为.mp3格式的实战详解

pip install ncmdump

import os
from ncmdump import dump

def convert_ncm_to_mp3(input_file, output_file):
    # 解密 .ncm 文件
    dump(input_file, output_file)

if __name__ == '__main__':
    input_file = '周传雄 - 青花.ncm'
    output_file = '周传雄 - 青花.mp3'
    convert_ncm_to_mp3(input_file, output_file)
    print(f'转换完成: {output_file}')
